Fermentation, biodegradation and tensile strength of poly(3-hydroxybutyrate- co-4-hydroxybutyrate) synthesized by Delftia acidovorans
This study discusses poly(3-hydroxybutyrate-co-4-hydroxybutyrate) that is produced by Delftia acidovorans bacteria in fed-batch cultures from various carbon sources. The experimentally determined optimal fed-batch culture conditions are as follows: pH: 7.0, incubation temperature: 26 8C, incubation time: 72 h, and concentration of carbon source: 10 g/L. The maximum 4HB unit composition of P(3HB...
متن کاملOptimum pH and temperature conditions for xylose fermentation by Pichia stipitis.
Pichia stipitis NRRL Y-7124 is a xylose-fermenting yeast able to accumulate ca. 57 g/L ethanol. Because optimum process conditions are important, data were collected to determine the effects of temperature and pH on growth and fermentation rates and product accumulations. Temperatures (26-35 degrees C) providing optimum biomass and ethanol productivities did not necessarily provide maximum etha...
متن کاملGlycerol production by microbial fermentation: a review.
Microbial production of glycerol has been known for 150 years, and glycerol was produced commercially during World War I. Glycerol production by microbial synthesis subsequently declined since it was unable to compete with chemical synthesis from petrochemical feedstocks due to the low glycerol yields and the difficulty with extraction and purification of glycerol from broth. As the cost of pro...
متن کاملOptimum conditions for adsorptive storage.
The storage of gases in porous adsorbents, such as activated carbon and carbon nanotubes, is examined here thermodynamically from a systems viewpoint, considering the entire adsorption-desorption cycle. The results provide concrete objective criteria to guide the search for the "Holy Grail" adsorbent, for which the adsorptive delivery is maximized. It is shown that, for ambient temperature stor...
متن کاملOptimum conditions for protein extraction from tuna processing by-products using isoelectric solubilization and precipitation processes
The by-product from tuna processing is a potential source of edible protein. Therefore, it is very important to extract protein from such raw materials for human food. In this study the optimum pH for protein extraction from tuna by-products was optimized by using isoelectric solubilization and precipitation processes. The Response Surface Methodology (RSM) and the single factor model were used...
